TUI Calendar: Enter does nothing on a highlighted event (Day/Week), though the help bar shows "enter: open"

[albertreig]

What happens

In hey tui, Calendar section, Day or Week view: highlight an event with the arrow keys and press Enter. Nothing happens.

The context help bar shown while the content row is focused advertises enter open (from the generic content-row bindings in internal/tui/tui.go updateHelpBindings, ~line 743), the same hint that opens a thread in the Mail list. In the calendar Day/Week view that hint is dead — there is no key that opens/views the highlighted event.

Expected

Enter on a highlighted event opens it (the same result as e today), consistent with the help bar and with Mail, where Enter opens the selected row.

Actual

internal/tui/calendar.go:

• handleContentKey (~line 1058) has no "enter" case.
• handleArrowKey (~line 1133) only handles "enter" in Year view (enterYearCell, stepping into a day cell). In viewDay / viewWeek it returns handled == false.
• So Enter falls through to v.contentVP.Update(msg) (viewport scroll) and is a no-op.

The only way to open/inspect an event is e (opens the edit form, eventFormEdit). There is no read-only "view" mode — eventFormMode is just eventFormCreate / eventFormEdit.

Suggested fix

In handleContentKey / handleArrowKey, for viewDay and viewWeek, map enter to open the selected recording when there is one:

case "enter":
    if event, ok := v.selectedRecording(); ok {
        return v.startEventForm(eventFormEdit, event), true
    }

Year view keeps its two-stage behavior (Enter steps into a cell; once inYearCell, Enter could then open the selected event). Happy to send a PR.

Environment

• hey-cli 1.4.3 (Linux, installed via mise)
